SUMMARY The effect of predators and parasites on the mortality of wheat bulb by pupae was studied in the field at Rothamsted Experimental Station, Harpenden, Hertfordshire, from 1964 to 1966. In two populations of pupae studied, 34 and 27 per cent were destroyed by predators, possibly carabid beetles. In two other populations, losses of 15–61 per cent and 29 per cent were also ascribed to predators. A fualher 0·5–5·8 per cent of pupae were killed by parasitic Hymenoptera.
